Giving is governed by the same rules as trading, but you get nothing in return. So you can't give someone a GUAL card as it is not an Item. However, as you an play a GUAL on anybody, you could negotiate a deal with someone for you to play that card on them. This only works for GUALs, as the FAQ says we can play them on other players, you can't do it for other cards, like monsters or Classes.

You can only discard cards that the rules say you can discard. I can't think of any specific types of cards that you can discard directly from your hand.
